Abstract excerpt

KEY MESSAGE: Leaf and panicle blast resistances were moderately correlated and controlled by several genes, including Pi2/Pi9 and Pi33. GWAS-based marker weighting increased GBLUP predictive ability by up to 37% across two rice populations. Breeding for blast resistance remains a high priority in rice (Oryza sativa L.) improvement, yet the genetic complexity of leaf blast (BL) and panicle blast (PB) continues to...
